When colour scopes came out no one noticed. We didn’t even put the rings on the probes anyway
As for the customer insisting they’re not stupid, that’s a fairly large assumption.
That's the point I just made... probe colours has nothing to do with the screen. Being able to change the screen colours is useful in its own right, has nothing to do with freaking probes, hence why it was implemented in the old TDS scopes where they recognized that basic, obvious fact.
Soon car makers will offer their cars in only one colour, the colour of your house, so that the two match. What if the owner wants a different colour ? No, your house is white, I will only sell you your car in white. Model T tried that with black IIRC, but somehow, go figure, over time people really wanted other colours, strange...
I am trying to decide if I should keep my BC307 and BC368 trannystors...
I'll have any colour as long as it's black
As for the BC307 and BC368, best to think about it in this way:
TUN and TUP. Transistor Universal NPN and Transistor Universal PNP:

Or just do what I did which was throw them all away by accident and just buy a shit ton of 2n3904, 2n3906, pn2222a, bd139 and bd140 and be done with it (that's 90% coverage of all normal electronics requirements)
Yeah I knew you would say that !
I am leaning towards an intermediary solution... all these transistors I did not pay for, they are just there, so it's a bit of a waste to throw hundreds of them.
So what I am doing now is throw away those that I have just one or two or three of, because rearranging my drawers is a lot work just to insert a couple transistors. So i am going to endure the pain and take the time, I am not, anymore, going to do it for each and every tiny transistor I have... waste of precious drawers and real estate.
So ouf othe hundreds of TO92 transistors I sorted today from that bag I posted last night.... I am keeping only those that
- I already had in stock hence I can just add to an existing drawers, zero work involved
- There are many of, and their spec is something I don't have yet.
But those with inferior specs than what I have, or similar specs but too few of them... I scrapped them.
Doing that, I now have only 3 new transistors to add to my inventory, instead of 2 dozens..... that's much more manageable.
The thing is too, is that I do like to keep some old models since I seem to like older TE, and it's just cool when I need to replace an old transistor and look in my drawer and... YEAH, I have the exact same one !!
Like just the other day when I fixed that Matra Missile 400HZ 3 phase inverter and I needed to replace a 2N1711 NPN, and I happened to have some in stock !
Longer term, I think my compromise will evolve one step further. For example I think that to make best use of my drawers, I will keep only a very few TUN TUP and keep my older and more numerous transistors, but simply put them in small plastic zip bags and stuff them all in a box. This way I can still find them if I ever need them for an old TE, but they take very little space and don't waste precious drawer real estate.
Sounds like the best compromise in my particular case.
Unlike you I just can't get myself to throw stuff away, never mind TE !
